Optical profilometry

Optical profilometry is a non-contact method used to measure the surface texture and topography of objects with high precision. It uses light, often laser or white light, to scan the surface and collect detailed data about its height variations and features. By analyzing how light interacts with the surface, it creates a 3D map that reveals bumps, valleys, and surface roughness. This technique is widely used in manufacturing, quality control, and scientific research because it provides fast, accurate measurements without damaging the sample.
